Then in Bomb Disposal players will be fighting for control of a robot that can either crack encrypted email terminals, or add additional levels of security.

There's also a new two part Headquarter Battle crusade in which eight heroes and eight villains face off against each other. The former have to take over the Hall of Doom while the latter must breach The Watchtower.

Finally, the first light-powered Legend characters are being introduced to multiplayer combat. You'll have access to Kilowog, a Green Lantern, and Amon Sur, a member of the Sinestro Corps.

See the screenshot gallery below for a closer look at all this new stuff.

The expansion will be a free download for Legendary members, while everyone else will have to reach for their wallets. A price tag hasn't yet been confirmed.
